Problems solved by technology

[0006] The problems in the above-mentioned technology are: 1. The structure is complicated and the cost is high, and the lifting and puncturing structure needs to be designed separately; 2. The position of the liquid storage barrel is relatively high, otherwise the puncture tube cannot enter the barrel; When the liquid-permeable barrel is sealed, some slag may fall into the liquid barrel, so it is necessary to further increase the filter components, which further increases the cost and the complexity of the structure

Abstract

The invention discloses a connection assembly for connecting a liquid storage barrel and a liquid outlet pipe in a liquid vending device, and relates to the technical field of automatic vending devices. The connection assembly includes a liquid outlet connector which is arranged in an opening of the liquid storage barrel and is connected to a liquid pumping pipe, and an intermediate connection sleeve connected to the opening of the liquid storage barrel and the liquid outlet pipe; a one-way air inlet channel and a normally closed one-way liquid outlet channel are arranged between the intermediate connection sleeve and the opening of the liquid storage barrel; the one-way liquid outlet channel includes a liquid outlet one-way valve and an intermediate connector; and the one-way air inlet channel includes a waterproof breathable valve fixed on the intermediate connection sleeve, an annular cavity formed between an outer wall of the liquid outlet connector and an inner wall of the openingof the liquid storage barrel, and an air inlet one-way valve. The one-way air inlet channel and the one-way liquid outlet channel are arranged in a sealed space, outer impurities can be prevented from entering the liquid storage barrel; and the waterproof breathable valve can prevent pathogenic bacteria and micro particles in air from entering the liquid storage barrel and affecting liquid in theliquid storage barrel.

Description

technical field [0001] The invention relates to the technical field of self-service vending equipment, in particular to a connection assembly used for self-service liquid vending equipment for quickly connecting a liquid outlet pipe and a liquid storage barrel. Background technique [0002] With the advancement of science and technology and the gradual development of mobile payment, the application of vending machines has become more and more popular. All walks of life have vending machines suitable for their own products, such as common vending machines, bottled beverage self-service vending machines, movie Ticket self-service ticket machines, etc., but there are few vending machines for bulk drinks. [0003] Bulk beverages have advantages that bottled beverages cannot replace. On the one hand, they can guarantee their freshness without adding preservatives. On the other hand, they can purchase appropriate quantities according to their own needs to avoid waste. In order to...
